Microwave radiofrequency ablation of the liver involves inserting a radiofrequency needle into the tumor via ultrasound guidance, calculating the radius of microwave radiofrequency radiation, and killing the tumor cells as well as achieving cure after multiple microwave treatments. It is generally used to cure the tumor locally with high energy and heat, and can achieve the same curative effect as surgery. Microwave radiofrequency ablation can be done for smaller tumor diseases or hepatic hemangiomas in the early stages, while aggressive surgical treatment needs to be considered for larger masses occupying the liver. Because microwave radiofrequency ablation has strict requirements for its size, if the tumor is larger than 5cm, there is a possibility of residual cancer cells or incomplete curing of the lesion and further possibility of recurrence or metastasis. Therefore, for patients with larger tumors, surgery is the preferred treatment option. After surgery, if the patient has recurrence of small liver masses, radiofrequency ablation can be considered for further treatment.
